Panchromatic Hubble Andromeda Treasury XII. Mapping Stellar Metallicity Distributions in M31
Dylan Gregersen, Anil C. Seth, Benjamin F. Williams +14
We present a study of spatial variations in the metallicity of old red giant branch stars in the Andromeda galaxy. Photometric metallicity estimates are derived by interpolating is…
The Panchromatic Hubble Andromeda Treasury XI: The Spatially-Resolved Recent Star Formation History of M31
Alexia R. Lewis, Andrew E. Dolphin, Julianne J. Dalcanton +15
We measure the recent star formation history (SFH) across M31 using optical images taken with the \texit{Hubble Space Telescope} as part of the Panchromatic Hubble Andromeda Treasu…
The High-Mass Stellar Initial Mass Function in M31 Clusters
Daniel R. Weisz, L. Clifton Johnson, Daniel Foreman-Mackey +16
We have undertaken the largest systematic study of the high-mass stellar initial mass function (IMF) to date using the optical color-magnitude diagrams (CMDs) of 85 resolved, young…
PHAT Stellar Cluster Survey. II. Andromeda Project Cluster Catalog
L. Clifton Johnson, Anil C. Seth, Julianne J. Dalcanton +12
We construct a stellar cluster catalog for the Panchromatic Hubble Andromeda Treasury (PHAT) survey using image classifications collected from the Andromeda Project citizen science…
